Hazrat Abu Saeed Khudri (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) took my hand and said, "Abu Saeed! There are three things that whoever says them will enter Paradise." I asked, "O Messenger of Allah (peace and blessings be upon him), what are those things?" He said, "Whoever is pleased and content with Allah as his Lord, Islam as his religion, and Muhammad (peace and blessings be upon him) as his Messenger." Then he said, "Abu Saeed! There is also a fourth thing whose virtue is equal to the distance between the earth and the sky, and that is striving in the path of Allah (jihad fi sabilillah)."
